currently our club use Inverse, another local club use Giordana. Our club has used Impsport, Alexa( also UK I believe), Tal (endure), Bioracer. Wasn't impressed with Tal, Alexa or impsport if I am honest.

Impsport sizing is err.... generous, so much so that in my last club the I have worn absolutely none of the £300+ of kit that I bought from their order because none of it fitted.
Current club kit is via MStina (Italian), I have some from events I've done in Italy previously and am quite impressed with the quality.
